Hi. Been shopping around for an mhl cable. Found one I like but I saw something I didn't see on other descriptions and thought I'd familiarize myself with it. However everything I read about HDCP explains it very little or rambles on about something else. *What exactly does that mean/do? (HDCP) *Will it keep me from streaming videos from the internet, or did I understand it wrong? *Or movies I converted on my PC? *Is this on every mhl cable? Thanks in advance to anyone that could clear this up for me.
